The Kungurian saliferous sediments of the Pre-Caspian sedimentary basin represented by thick stratum of rock salt with interlayered lenses of anhydrites, terrigenous and carbonate rocks. Initial thickness of these sediments estimated as 4000–4500 m at the center of the depression and 1000–2000 m on the edges of the basin. The processes of halokinesis led to formation of more than 1200 salt dome structures represented by salt diapirs and walls, ridges and salt pillows. Number of salt dome related structures of Mesozoic clastic deposits revealed by seismic exploration carried out in 70–90′s of last century are quite common on the south-eastern part of the Pre-Caspian Sedimentary basin. Most of hydrocarbon pools in post-salt clastic rocks have been discovered on fault-related anticline prospects which are derived from salt tectonics morphologically variable (Munyithya et al. Petrol Explor Prod Technol 10: 2257–2267. https://doi.org/10.1007/s13202-020-00917-1, 2020). Other potential traps anticipated in the area are stratigraphic traps, pinch-out and unconformity-related traps, trapped by salt domes and walls or by salt overhang, etc.

东南前里海的盐后捕集机制及其在石油勘探中的应用

前里海沉积盆地的昆古纪含盐沉积物以厚厚的盐岩层为代表，中间夹有硬石膏，陆源和碳酸盐岩。这些沉积物的初始厚度在凹陷中心估计为4000-4500 m，在盆地边缘则为1000-2000 m。盐动力学的过程导致形成了1200多个盐穹顶结构，这些盐穹顶和盐壁和墙，山脊和盐枕代表着。上世纪70-90年代进行的地震勘探揭示的中生代碎屑岩盐穹顶相关结构的数量在里海前沉积盆地的东南部相当普遍。盐后碎屑岩中的大多数油气藏都是在断层相关的背斜前景上发现的，这些断层是从盐构造学形态上可变的（Munyithya等人，Petrol Explor Prod Technol 10：2257-2267。https://doi.org/ 10.1007 / s13202-020-00917-1，2020）。该地区预期的其他潜在圈闭有地层圈闭，与收缩和不整合有关的圈闭，被盐穹顶和壁或盐悬突等困住。
